Chemo-enzymatic derivatization (GalNAzylation, biotinylation) of O-GlcNAcylated recombinant human tau, trypsinization, enrichment via coupling to streptavidin beads, and release of tagged peptides by β-elimination – Michael addition reaction. nLC-HRMS (Q Exactive HF) analysis of final extract to monitor sulfited peptides for the localization of tau O-GlcNAcylation sites. Data were acquired in data dependent MS2 (ddMS2) mode and for low abundant O-GlcNAc peptides also in parallel reaction monitoring (PRM) mode.
